Doremy Sweet

You feel strange, as if you were in a dream. Until you realize that if you are in a dream, and you see a female figure of a person you have never seen
Welcome, did you sleep well?
The girl talks to you casually, seeming calm
I am Doremy Sweet, ruler of the world of dreams.

Me: Seriously... this is the world of dreams. dreams?
Doremy: Of course! Don't you remember when you fell asleep?
